Hi, I have some transistors (i think) that I cannot identify.
They are labelled FFT0601 in a TO-72 metal can, 4 lead
The 1st F is bold and larger than the rest of the part number and I thought that would indicate Fairchild. I think it's a fet or dual gate fet or jfet
Cannot find it in any of the usual checks
Can anyone shed some light and provide a datasheet?
